Prior to I-25, there was a different main highway that connected Denver to several of the Northern Front Range cities in Colorado. The number of this highway has changed a few times during the past century, but its general corridor has remained the same: it still runs through Ft. Collins, Loveland, Berthoud, Longmont, Lafayette, Broomfield, Westminster, and Denver. Not all of those cities had even been established at the time of the 1916 map shown below, but the highway corridor running along the Northern Front Range is readily apparent (going forward I will refer to this road as the NFRH, for "North Front Range Highway"):
US 87 and US 287 converge in Dumas, Texas, and share about 49 miles of pavement down to Amarillo, where the two routes separate again.

The three branches of the Concho River all converge in San Angelo; that was illustrated on this other slogan from days gone by:
When the US highway system was inaugurated in late 1926, the only US route to initially serve San Angelo was US 385 (that is, the original US 385, not the current US 385). The new designation was added to Texas State Highway 9:

Today, Denver is served by seven different US routes (shown above), but when the US highway system was first commissioned in late 1926, only three routes went through Denver. AASHO officials acknowledged the city's importance by placing it at the junction of a major north-south route (US 85, which ran from a Canadian port of entry almost to Mexico) and a transcontinental east-west route (US 40, which connected Atlantic City NJ to the San Francisco Bay Area):
